IPT Economical Residual Hardness

Measurement of the colour change of the complex formed by reaction of hardness with Eriochrome black in a buffered solution.

0,0 – 0,25 – 0,5 – 0,8 – 1,5 – 3,0 ppm CaCO3

250

Purified, potable and of thermal circuits

• 1 bottle 15cc titrant hardness
• 1 bottle 15cc indicator hardness
• 1 test tube 10cc
• 1 color scale with use directions

- The optical comparator contained in the package enables a color comparison between two test tubes containing the same amount of water, which increases accuracy.
- HYDROCHECK kits (which can be purchased directly) allow many accurate analyses to be carried out at a very low cost per analysis. If precision is not particularly important and the analyses to be carried out are few in number, it may be worthwhile using DROPS kits, which cost considerably less per package (to be purchased through dealers).
